Anyone get a bfp after their period was due?

Brandi-lea • Khaleesi-May Dizney Van Vliet - my precious daughter born on 23.6.15 👶🏼🌸
So AF isn't here and was due yesterday, after multiple faint positives I tested today with a clear blue digi and weeks estimator and unfortunately, a rubbish bfn for me! I'm 14 dpo today, I thought I was 15dpi but turns out I actually O'd cd17 instead of 16 this months! Did anyone get a bfn at 14dpo then a bfp a few days later or so ?
